So you are getting some new car tyres and you are faced with the myriad of numbers and symbols that adorn a tyre’s sidewall. These markings provide vital information about the tyre’s size, type, performance capabilities, and safety ratings. This comprehensive guide aims to demystify these markings, helping you to make informed decisions about tyre size, ratings, and labels when getting a tyre service.
Understanding Tyre Sizes
One of the first steps in selecting the right tyre is to understand its size. Tyre size is a series of numbers and letters printed on the tyre’s sidewall, indicating its specifications.
Here’s how to decode this information:
Example Tyre Size: 205/55R16 91V
205 indicates the tyre’s width in millimetres from sidewall to sidewall.
55 is the aspect ratio, which is the height of the tyre’s sidewall as a percentage of its width. In this case, the sidewall height is 55% of 205 mm.
R stands for Radial, indicating the tyre’s construction type. Radial tyres are the most common and feature layers of fabric with cords running at right angles to the circumference.
16 denotes the diameter of the wheel rim in inches that the tyre is designed to fit.
91 is the load index, representing the maximum weight the tyre can safely support when fully inflated.
V is the speed rating, showing the maximum speed at which the tyre can carry a load under specified service conditions. V-rated tyres are approved for speeds up to 149 mph.
Tyre Ratings
Tyre ratings are crucial indicators of a tyre’s performance capabilities, including how well it can handle certain loads and speeds, as well as its efficiency and safety in various conditions.
Performance Ratings:
Tyres undergo rigorous testing to gauge their ability to perform under different conditions. This includes evaluating how the tyre behaves in wet conditions, its impact on fuel economy, and the noise it generates while rolling. The European Union, among others, has standardised tyre labels to help consumers compare tyres more easily.
Fuel Efficiency: Indicated by letters from A to G, with A being the most fuel-efficient. This rating shows how well the tyre rolls and its impact on fuel consumption.
Wet Grip: Also rated from A to G, this rating tells you how well the tyre can stop on wet roads. A higher rating means shorter stopping distances in wet conditions.
Noise Level: Measured in decibels, this rating helps you understand how much noise the tyre generates. A lower number indicates a quieter tyre.
Load Index and Speed Rating:
Beyond performance, tyres are also rated for their load capacity and maximum safe speed.
The load index is a numerical code associated with the maximum weight a tyre can support when properly inflated. It’s paramount to choose tyres that match or exceed the manufacturer’s recommended load index to maintain vehicle safety and performance.
The speed rating, denoted by a letter from A to Z, specifies the maximum speed at which the tyre can safely carry the load indicated by its load index. Matching or exceeding your vehicle manufacturer’s recommended speed rating is crucial for maintaining your vehicle’s handling characteristics.
